We're grabbing raw pixel data but we're not really controlling the camera itself. Now, if we open the camera dialog again during preview, we can use Windows' sliders to adjust zoom and such. Gotcha... maybe if the camera's software itself has an API, but not that important for anything I'd be looking to do. You've done quite enough, thank you! :-D
I did some googling on generating an AVI, I found something about using FFMPEG for turning a bunch of still images into a movie, so maybe that could work (just saving each frame to a file and then shelling out to FFMPEG)?
I'll play with this stuff later. One thing I want to try is "video echo"... Merging the images from the camera as they come in with what's already on the screen... Maybe it will show trails or look trippy. Another idea is having 2 laptops each with a webcam, and having laptop #2 send its pictures over a LAN to laptop #1 and merging them in some funky way. I don't know what kind of throughput it would need for 320x240 resolution at 30 FPS? This stuff is fun to play with, that's for sure :-) For merging the camera feeds in real-time, you’d likely need a solid network connection between the two laptops. For 320x240 at 30 FPS, the required bandwidth would be around 1.5 Mbps (assuming uncompressed video). You could probably get away with even lower if you compress the video a bit.

Yeah, this would be over a wired LAN connection with 2 (or maybe 3-4?) laptops sitting near each other. All each would really need to do is continually save the current frame of video to an image file in a folder on laptop #1, and it would just keep reading them in and displaying them. The code already does the saving to a BMP file and QB64PE can load an image from a file, so it would just need 2 or more of these programs running and saving files over the LAN. It shouldn't be hard to make a proof of concept when I get a minute at the PC...
Hey @SpriggsySpriggs, is there a way to get it to save the single frame to a compressed format like JPG instead of BMP?

Of course. Open BMP file with the _Loadimage function and save it as a JPG with the _SaveImage function.

Of course. Open BMP file with the _Loadimage function and save it as a JPG with the _SaveImage function. That's definitely a way! Though the point was to compress the file so it could be sent to the other computer faster (30 FPS per camera), so I'm not sure if the round trip of loading / saving will actually speed anything up? Then again, maybe it would, with that happening on the local hard drive*, where the compressed image getting sent over the wire opens the bottleneck? Only one way to find out! 
*What if the local file operations were done on a virtual RAM drive**, would that add any speed? Then again, these days with SSDs, which pretty much ARE RAM drives, are we already doing that? Do I enjoy overthinking this crap?? Never mind... carry on!
**Are those even a thing anymore?

The idea for making AVI using an image sequence would be a little silly at this point. Might as well make it from scratch from frame data and such. As for sending over TCP/IP, you'd probably want super low resolution and to use a good compression algorithm. Maybe _DEFLATE$. Remember, all the frame data is lossless.

And a video showing the kind of retro effect you can get with the scanline effect, green cranked up, and ghosting enabled. You may need to watch the video in full-screen mode to see the effect properly.

(03-02-2025, 01:45 AM)SpriggsySpriggs Wrote: The idea for making AVI using an image sequence would be a little silly at this point. Might as well make it from scratch from frame data and such. As for sending over TCP/IP, you'd probably want super low resolution and to use a good compression algorithm. Maybe _DEFLATE$. Remember, all the frame data is lossless.
Making an AVI from scratch from frame data seems like a non-trivial task, and I wasn't finding any QB64 examples, but lookie here - are Microsoft's APIs coming to the rescue once again? There's an example at
https://www.wischik.com/lu/programmer/avi_utils.html
that references "avi_utils.h". I'll have to give it a try...

I don't think we'll be able to use that. It has interfaces and I have yet to get a single interface thing to work in QB64.

Maybe one of the usual suspects can help figure it out? (@Petr has done some nice work with sound files, so he'd be the horse I'd bet on for figuring out how to write an AVI from scratch - but that all depends on his actually being interested!)
Me, I'm just a lowly BASIC programmer, which is why I'd resort to something like FFMPEG to make a movie from still images! LoL
I'll post a seperate question for this, and see if anyone bites...
